Terzaghi Dam
Terzaghi Dam is the key diversion dam in BC Hydro's Bridge River Power Project. It forms the project's largest reservoir, Carpenter Lake west of Lillooet. Originally known as the Mission Dam, it was renamed Terzaghi Dam in 1965 to honor Karl von Terzaghi, the civil engineer who founded the science of soil mechanics. It is located about 30 km up the Bridge River from its confluence with the Fraser. It stands at the head of the Big Canyon of the Bridge River, completely blocking the river, which is diverted through two tunnels through Mission Mountain to a pair of powerhouses on Seton Lake. The difference in elevation between Carpenter Lake, the reservoir formed by Terzaghi Dam, and the two powerhouses on Seton Lake is c. 410 m, which in combination with the flow of the entire Bridge River generates 480 megawatts in electrical power. Completed in the 1950s, it was the expansion of a concept first launched in the 1920s by the Bridge River Power Development Co. but abandoned due ...

As of 2014, 95 per cent of the province's electricity was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Megawatts
The watt (symbol: W) is the unit of power or radiant flux in the International System of Units (SI), equal to 1 joule per second or 1 kg⋅m2⋅s−3. It is used to quantify the rate of energy transfer. The watt is named after James Watt (1736–1819), an 18th-century Scottish inventor, mechanical engineer, and chemist who improved the Newcomen engine with his own steam engine in 1776. Watt's invention was fundamental for the Industrial Revolution. Overview When an object's velocity is held constant at one metre per second against a constant opposing force of one newton, the rate at which work is done is one watt. : \mathrm In terms of electromagnetism, one watt is the rate at which electrical work is performed when a current of one ampere (A) flows across an electrical potential difference of one volt (V), meaning the watt is equivalent to the volt-ampere (the latter unit, however, is used for a different quantity from the real power of an electrical circuit). : \mathr ...

Dams In British Columbia
A dam is a barrier that stops or restricts the flow of surface water or underground streams. Reservoirs created by dams not only suppress floods but also provide water for activities such as irrigation, human consumption, industrial use, aquaculture, and navigability. Hydropower is often used in conjunction with dams to generate electricity. A dam can also be used to collect or store water which can be evenly distributed between locations. Dams generally serve the primary purpose of retaining water, while other structures such as floodgates or levees (also known as dikes) are used to manage or prevent water flow into specific land regions. The earliest known dam is the Jawa Dam in Jordan, dating to 3,000 BC. The word ''dam'' can be traced back to Middle English, and before that, from Middle Dutch, as seen in the names of many old cities, such as Amsterdam and Rotterdam. History Ancient dams Early dam building took place in Mesopotamia and the Middle East. Dams were used ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shalalth, British Columbia
Shalalth and South Shalalth are unincorporated communities on the northern shore near the western end of Seton Lake in the Squamish-Lillooet region of southwestern British Columbia. The localities are by road about northwest of Lillooet, but only by rail. First Nations The word Shalalth (pronounced Sha-LATH and spelled Tsal’álh in St'at'imcets, the Lillooet language) means simply "lake" or, particularly, ''the'' lake, meaning Seton Lake. Indigenous peoples form the majority of the population in the valley and in the Shalalth environs, which is one of the main communities of the Seton Lake First Nation Band of the St'at'imc (Lillooet) Nation. A First Nations school, small timber mill, and various small businesses operate. In 1990s, the Seton Lake First Nation built a new residential subdivision named Ohin, further east than the traditional Shalalth rancherie area (beginning at the base of the Mission Mountain Road to a few coves east). The name Ohin, pronounced ''OO(kh)win' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Minto City, British Columbia
Minto City, often called just Minto, sometimes Minto Mines, Minto Mine, Skumakum, or "land of plenty", was a gold mining town in the Bridge River Valley of British Columbia from 1930 to 1936, located at the confluence of that river with Gun Creek, one of its larger tributaries. The mine prospect was never much successful although a model townsite was built by promoter "Big Bill" Davidson, who imported soil to build a specially-built rodeo ground and baseball diamond on the rocky site. The larger mine of Bralorne was nearby. The mine shut down in 1936 due to productivity issues, but restarted in 1940. The valley has since been significantly altered when most of the vestiges of the town were inundated by the waters of the Carpenter Lake reservoir following completion of the Bridge River Power Project. In 1941, around two dozens of Japanese Canadian families were relocated to Minto Mine, and ordered to live in the empty miners' houses due to the impacts of the war. The community w ...

World War II
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Post-war Boom
In Western usage, the phrase post-war era (or postwar era) usually refers to the time since the end of World War II. More broadly, a post-war period (or postwar period) is the interval immediately following the end of a war. A post-war period can become an interwar period or interbellum, when a war between the same parties resumes at a later date (such as the period between World War I and World War II). By contrast, a post-war period marks the cessation of armed conflict entirely. Post–World War II Chronology of the post–World War II era The term "post-war" can have different meanings in different countries and refer to a period determined by local considerations based on the effect of the war there. Some examples of post-war events are (in chronological order) ;The Cold War (1947–1991) The Cold War was a geopolitical conflict between the capitalist and liberal democratic United States of America, the authoritarian and Communist Marxist–Leninist Union of Soviet Soc ...

British Columbia Electric Railway
The British Columbia Electric Railway (BCER) was an historic railway which operated in southwestern British Columbia, Canada. Originally the parent company for, and later a division of, BC Electric Company (now BC Hydro), the BCER assumed control of existing streetcar and interurban lines in southwestern British Columbia in 1897, and operated the electric railway systems in the region until the last interurban service was discontinued in 1958. During and after the streetcar era, BC Electric also ran bus and trolleybus systems in Greater Vancouver and bus service in Greater Victoria; these systems subsequently became part of BC Transit, and the routes in Greater Vancouver eventually came under the control of TransLink. Trolley buses still run in the City of Vancouver with one line extending into Burnaby. History Streetcar and interurban services were inaugurated in southwestern British Columbia between 1890 and 1891, operated by the following companies: * National Electric Tramw ...

Great Depression
The Great Depression (19291939) was an economic shock that impacted most countries across the world. It was a period of economic depression that became evident after a major fall in stock prices in the United States. The economic contagion began around September and led to the Wall Street stock market crash of October 24 (Black Thursday). It was the longest, deepest, and most widespread depression of the 20th century. Between 1929 and 1932, worldwide gross domestic product (GDP) fell by an estimated 15%. By comparison, worldwide GDP fell by less than 1% from 2008 to 2009 during the Great Recession. Some economies started to recover by the mid-1930s. However, in many countries, the negative effects of the Great Depression lasted until the beginning of World War II. Devastating effects were seen in both rich and poor countries with falling personal income, prices, tax revenues, and profits. International trade fell by more than 50%, unemployment in the U.S. rose to 23% and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Seton Lake
Seton Lake is a freshwater fjord draining east via the Seton River into the Fraser River at the town of Lillooet, about long, in area and lies at an elevation of . Its depth is . The lake is natural in origin but was raised slightly as part of the Bridge River Power Project, the two main powerhouses of which are on the north shore of the upper end of the lake near Shalalth. At the uppermost end of the lake is the community of Seton Portage and the mouth of the short Seton Portage River, which connects Anderson Lake on the farther side of the Portage to Seton Lake. The Seton Portage River is the main source of natural inflow to Seton Lake, and is primarily fed by Anderson Lake but also by Whitecap Creek, which has its origin on the east slopes of Whitecap Mountain, the highest in the Bendor Range, and by Spider Creek, which has its origin on the north slopes of an unnamed summit to the south of Seton Lake, which happens to be the highest of the Cayoosh Range which lines the sout ...

Bridge River Power Project
The Bridge River Power Project is a hydroelectric power development in the Canadian province of British Columbia, located in the Lillooet Country between Whistler and Lillooet. It harnesses the power of the Bridge River, a tributary of the Fraser, by diverting it through a mountainside to the separate drainage basin of Seton Lake, utilizing a system of three dams, four powerhouses and a canal. Discovery and original development The potential for the project was first observed in 1912 by Geoffrey Downton, a land surveyor, visiting the goldfield towns in the area who noticed the short horizontal distance between the flow of the Bridge River, just above its impressive canyon, and the much-lower Seton Lake. It was fifteen years before this observation was put to task, and not until 1927 that a private company first bored a tunnel through Mission Ridge (also known as Mission Mountain), which separates the basins of the Bridge and Seton systems. This tunnel was completed in 193 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mission Ridge (British Columbia)
Mission Ridge, also known as Mission Mountain, is a ridge in the Bridge River-Lillooet Country of the South-Central Interior of British Columbia, Canada, extending westward from the town of Lillooet along the north side of Seton Lake to Mission Pass, which is immediately above and to the north of the lakeside community of Shalalth. The road over the pass is also known as Mission Mountain, which is short for "Mission Mountain Road". Mission Creek lies on the north side of the pass, and is a tributary of the Bridge River, the lower reaches of which lie on the north side of the ridge, and which was the only road access into the upper Bridge River Country before the construction of a road through the Bridge River Canyon in the mid-1950s opened that region up to road access from the lower Bridge River valley and the town of Lillooet via the community of Moha. Most, or virtually all, of the ridge, is Indian Reserves, notably Slosh 1, under the administration of the Seton Lake Indian ...
